Abstract
Plasma desorption induced by the impact of Cf-252 fission fragments wa s used to study the emission of positive cluster ions from a lanthanum nitrate, La(NO3)(3) . 6H(2)O, substrate. Two large series of peaks we re observed. One corresponded to the addition of LaO+ to a repeating b ase unit of La2O3. A less intense series contained the same base unit, with H+ attachment. Neither series contained clusters that reflect th e structure or stoichiometry of the original sample. We propose that t he cluster ions are produced by high temperature and pressure chemical reactions inside the fast ion track.
